When a commercial property owner in Anaheim reached out to Lazaro’s Roofing Inc., the problem was hard to ignore. Years of deferred maintenance had taken their toll — a flat roof showing widespread membrane failure, pooling water around clogged drains, cracked and bubbling sections where moisture had worked its way underneath, and flashing that had long since pulled away from the parapet walls. It wasn’t just an eyesore. It was a liability. And it needed a team that actually knew what they were doing.
That team was us. If you’ve been searching for a dependable roofing in Anaheim CA contractor — one that shows up on time, communicates clearly, and leaves a job site better than they found it — you’ve found the right place.
The Condition Before We Started
The roof in question was a commercial flat roof covering a mid-size commercial building in Anaheim. Like many flat roofs in Southern California, it had been patched over the years — but patching can only go so far. What we found when we got up there told the full story:
- Membrane deterioration: The existing single-ply membrane had cracked and separated in multiple locations, especially around penetrations and edges.
- Standing water: Improper drainage had allowed water to pool, accelerating the breakdown of the roof surface.
- Compromised flashing: The metal flashing along the parapet walls had lifted and, in several spots, completely detached — creating direct water entry points.
- Interior damage risk: Evidence of moisture intrusion near HVAC curbs suggested the damage was already working its way inside.
This is the kind of job that requires more than a patch kit and a prayer. It called for a full commercial roofing service — tear-off, replacement, and proper waterproofing from the substrate up.
What Lazaro’s Roofing Inc. Did
Our crew began with a full tear-off of the old membrane, clearing the roof deck down to a clean, inspectable surface. This step matters more than most people realize — installing new materials over a failing substrate just transfers the problem, it doesn’t fix it.
Once the deck was clear and inspected for structural integrity, here’s what we did:
1. Deck Repair and Preparation Any sections showing soft spots, rot, or compromised decking were addressed before a single new layer went down. We don’t cut corners on prep — because prep is what makes the finished product last.
2. New Insulation Layer We installed a fresh layer of polyisocyanurate (polyiso) insulation board, tapered to promote positive drainage toward the roof drains. In Southern California’s heat, proper insulation isn’t just about energy efficiency — it protects the roof membrane from thermal stress that causes premature aging.
3. Single-Ply TPO Membrane Installation We applied a high-quality TPO (thermoplastic polyolefin) membrane across the entire roof surface, heat-welded at all seams for a watertight bond that holds up through rain, UV exposure, and temperature swings. TPO is one of the top choices for commercial flat roofing — reflective, durable, and backed by strong manufacturer warranties.
4. Flashing and Detail Work Every penetration, drain, curb, and parapet wall received new flashing, installed with care and sealed properly. This is where a lot of roofing jobs fall short — the field installation looks fine, but the details are rushed. Not with us.
5. Final Inspection and Cleanup Before we left, we walked the roof with the property owner, pointed out everything we’d done and why, and made sure drainage was flowing correctly. The job site was left clean. That’s not optional at Lazaro’s — it’s standard.

After: A Roof That’s Built to Last
The finished roof was a dramatic transformation. Where there had been cracked, blistered membrane and lifted flashing, there was now a clean, white TPO surface sealed tight from edge to edge. The drains were clear and properly pitched. The parapets were flashed and caulked. The entire roof was waterproof, reflective, and ready for years of Southern California weather.
The property owner told us it was the first time in years he felt confident heading into a rainy season without crossing his fingers.
That’s the kind of result we go after on every job — residential or commercial, big or small.
